Abstract
Nowadays, more and more attention is paid to the warehouse environment. Traditional warehouse management often has problems such as low management efficiency, abnormal situation can not be timely monitored and dealt with, and a large number of pipelines need to be laid. Aiming at the above problems, this paper designs a warehouse environment monitoring system based on Internet of Things technology, including acquisition terminal, communication forwarding, local monitoring, remote monitoring and other parts.This design uses STM32 single chip microcomputer as the central controller, the sensor module includes temperature and humidity sensor DHT11, human pyroelectric sensor, its role is to monitor the temperature and humidity of the granary and whether there are people, to provide the most suitable storage conditions for the storage of goods; The execution module includes display module, door magnetic lock module, LED lamp module and buzzer alarm module, whose function is to adjust the temperature and humidity of the granary, switch the warehouse, alarm reminder, etc. In addition, the system also adds a WiFi module to realize remote viewing and remote control, making management more convenient and humanized. Finally, from the function and performance of the physical test, many tests show that the design scheme is simple and feasible, with the function of safe storage of goods, the system is safe, stable, reliable, and has practical application and promotion value.
